To all whom-it may concern: 1

Be it known that I, Enron J. Pa'mlsmfa citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Power Attachments for Kitchen Utensils and the like, of which the following is a specification.

This invention relates to improvements in power and supporting attachments for power-driven kitchen utensils such as are commonly used in the preparation of food. The object of the invention is to provide a useful and convenient source of motive power' which may be readily available for driving a variety of rotary kitchen utensils such as meat grinders, coifee mills, ice cream freezers, beaters, mixers, and the like.

A further object of the invention is to provide a new and useful mounting for the various utensils whereby the same can be interchangeably connected with the source of power and firmly supported while in operation.

In the accompanying disclosure the source of power is a flexible shaft driven from a motor, the latter being mounted upon a sink fixture and furnishing the power for a mechanical dish washing apparatus incorporated in the sink. While the utilization of a single source of power for operating both the dish washing apparatusas well as the various utensils used about a kitchen, it is manifest that such a combination is theresult of an effort to provide a complete and economical kitchen fixture, but does not preclude the use of a separate source of motive power and other supporting means than'a sink. The preferred'embodiment' of the invention has been illustrated in the accompanying drawings wherein: 1

Figure lis a general view in longitudinal vertical section through one portlon of a sink and showing the flexible shaft drive.

Figure '2 is a view in transverse vertical section, showing a utensil attached and in operative position.

Figure 3 is a view of the same utensll shown in Figure 2 with one of the attaching members shown in section.

Figure 4 is. an enlarged detail view in longitudinal section of the attaching and driving connections taken on line 4- -4.of

Figure 1,. and

. 'Figure5 is a perspective viewof the dissembled arts showing the utensil attachmg mem ers.

As hereinbefore suggested, the foundation l or main sup orting member of the devices to be driven 1s therear vertical anel 1 of a the-kitchen, either upon legs or wall brackw ets, as preferred. I

The sink is. equipped with the usual faucet and drain connections and further, :with a rotor or rotary water agitating elementjnot shown) located within a casing 4,.hav1n a perforated plate 5 opening into the bow 2 near its bottom. I The mechanical-dish washing means forms no part of the present invention, and therefore need not be described in detail other than to'point out that it is driven by a motor 7 which is suspended from the under side of the drain board 3,

by means of an invertedbase 8. The motor.

armature shaft has direct driving connec-' tion with the rotor shaft 10, journalled in a bearing 11, of the rotor casing, ounted on the rotor shaft 10 is a pinion 12 which meshes with a relatively large reduction gear wheel 13, supported in a journalframe 14, formed integral with the motor base.

This gear wheel has direct connection with. one end of a flexible shaft 16, enclosed within the usual flexible cable 17. I

The flexible shaft and the protectin cable lead u wardl behind the rear pane 1 of the sink, whic is spaced away from the wall and provides ample room for' the cable. Near the top edge of the panel andabove the drain board is'provid three openings, the central 0 ening being the-outlet from the drive sha As shown in 4, a bushing 18 is fitted in the opening flush with the outer face of the panel and extending beyond the rear face. To the rear end of the ushing is threaded a cap 19 into wh ch extends the end of the flexlble shaft 16, its surrounding cable 18 being coupled to the cap 19 b a threaded connection. The flex1 ble shasleeve 20 through a suitable swivel 'oint, saidsleeve bein journalled in roller rings 21 moun in the bushing 18. The sleeve is formed with a square socket 20 openin outward] with its entrance substanti y flush with the face of the panel.

is *connected at its end with a The openings on either side of the power opening or outlet just described, provide sockets for attaching the utensils to the panel and in driving connection with the flexible shaft. Each of these sockets comprise a bushing 22, fitting flush in the openings in the panel, with a cylindric cup-like casing 23 threaded onto the rearwardly projecting end. Within the casing 23 is mounted a plunger 24. backed by a coil spring 25. The bushing 22 has an irregular shaped slot 22 therethrough and which is elongated in a vertical direction with straight sides and curved ends as shown in Figure 5. The plunger 24 has a plug 24 shaped to conform to the slot, in t e ushing, and normally fits therein with its outer face flush with the surface of the anel and finished in the same manner. T us when a utensil is not in-use or has been removed from the panel the plunger comes forward and closes the openings in the attaching sockets so as to seal the cavities and prevent the accumulation of dirt or the entrance of vermin therein.

Having described the means for supporting and supplying power to the utensil to be operated, the co-acting parts of the utensil itself will now be described.

In the drawings a meat grinder 25 has been illustrated as typical of one of a variety of devices that may be attached to the power connection, some of which have already been mentioned. The mechanism of the utensil is therefore, of npimportance except that it has a rotative shaft for detachable connection with the flexible shaft. It may he therefore assumed that all the different utensils have the following parts in common with the meat grinder illustrated. Through the rear endof the frame or body projects the end of the shaft 26 or rotary element of the utensil, the same having a square end fitting the socket of the sleeve 20 at the power connection. (Figure 4). From either side of the utensil body extend lateral arms 27, 27 which carry at theirends, looking members 28, 28. Each locking member consisting of a shank 29 turning freely in the arm and having a locking head 30 at its inner end and win ed head 31 at its outer end. The lockin ead is shaped to conform with that o the slots in the attaching sockets and are adapted to enter said slots when the shank is turned to bring the head into registerin position with the slot. The shank is of su clent length to allow the head to clear the slot so that it can be turned through 90 or crosswise of the slot, thereby locking the parts together. Manifestly the plug 24* WlllCh normal] closes the slot is forced inwardly with t e plunger as the head 30 enters, but again closes the slot when the head is removed.' The utensil is further supported by means of a le 32 extending rearwardly and downwardly fr m the under side of said utensil having a foot 33 preferably covered by a resilient pad, and adapted to bear against the face panel below the power and attaching connections. It is contemplated that each of the several utensils Wlll be constructed with a siminserted in said socket, and a spring pressed plunger normally closing the opening to said socket.

2. In an apparatus of the character described, the combination of a supporting panel, a motor mounted adjacent said panel, a shaft connected with said motor and terminating in a sleeve journalled in said panel and having" an end substantially flush with the surface thereof, a socket in said panel, a spring pressed plunger in said socket normally closing said socket and a driven member having a shaft adapted for detachable driving connection with said sleeve and a locking member operative to engage said socket.

3. In a device of the character described,

the combination of a. supporting panel and a utensil adapted for detachable mounting thereon. a rotative power driven member journalled in said panel, said utensil being provided with a rotative member having a portion adapted to engage said power driven member, and means for supporting said utensil upon said panel in driving connection with said power driven member comprising a recess in said panel and a spring pressed plug in said recess normally held flush with the surface of said panel and closing the opening to said recess.

4-. In an apparatus of the character described, the combination of a supporting panel, a motor driven member journaled in said panel and having a socket opening flush with the surface thereof. and means for attaching an utensil to said panel in driving connection with said driven member, comprising a slotted member flush with the surface of said panel and adapted to be engaged by a locking member on said utensil, and a spring pressed plunger mounted immediately behind said slot and normally closing the same.

5. In an apparatus of the character described, the combination with a supporting panel, a motor driven member journalled in said panel, a socket said panel adjacent said sleeve and'a spring actuated plunger mounted in said socket and normally closing the entrance thereto.

6. The combination with a supportingpanel and a utensil adapted to be detachably mounted thereon, of a socket in said panel, a

lunger in said socket, a spring acting to yieldably hold said plunger to close the entrance to said socket, and adapted to be depressed upon the insertion of a locking member into said socket for locking connection with said panel.

7. The combination with a supporting panel and a utensil adapted to be detachably mounted thereon, of a motor driven power connection journalled in said panel, and attaching sockets adjacent said power connection adapted to receive locking members of said utensil, and spring pressed plungers mounted in said sockets and normally position'ed to close the same;

In witness whereof, I hereunto subscribe my name this 8th day of December, A. D., 1923.
